title: The correlation between crestal bone resorption and implant stability during healing period using resonance frequency analysis.
abstract: OBJECTIVE
  To detect the correlation between crestal bone resorption and implant stability during healing period using resonance frequency analysis (RFA).
  
  
  METHODS
  Twenty-two International Team for Implantology Straumann implants were placed in the posterior maxilla or mandible in 9 patients. RFA reading was taken immediately after implant placement. Periapical radiographs were taken, and the distance from the shoulder of the healing cap to the first bone-implant contact was measured, and the average mesial and distal distances were taken. Patients were followed up at 6 and 12 weeks for data collection.
  
  
  RESULTS
  At 6 weeks, the correlation between crestal bone resorption and implant stability was significant (Spearman correlation test, P < 0.05) and negative correlation coefficient (r) was -0.522. At 12 weeks, the correlation between crestal bone resorption and implant stability was not significant (Spearman correlation test, P > 0.05) and negative correlation coefficient (r) was -0.119.
  
  
  CONCLUSIONS
  There was a significant negative correlation between the crestal bone resorption and implant stability at 6 weeks, whereas the negative correlations between the crestal bone resorption and implant stability at 12 weeks were nonsignificant.
